TRAVELING-CYLINDER PRINTING-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 516,913, dated March 20,1894. Application ined Math '7, 189s. serial No. 464,930. (No model.)

To @ZZ whom it may concern.-

Be it known that I, CHARLES BUTTEEEIELD, a subject of the Queen of GreatBritain, residing at 181 Pym Street, in the town and county ofNottingham, England, have invented certain new and useful Improvementsin Traveling-Cylinder Printing-Machines, of which the following is aspecification, reference being made to the accompanying drawings, and tothe letters marked thereon.

The invention has for its object improvements in that description ofcylinder printing machines in which the type bed or lithographic stoneis held stationary while the cylinder having the paper thereon and thedamping and inking rollers are caused to traverse to and fro over thetype bed or lithographie stone, the cylinder being rotated whentraveling in the direction for printing and being held stationary whentravelingin the contrary direction after the printing has been effected.

My present invention relates to various improvements wllereby suchdescription of machines is rendered much firmer and the variousoperations more certain and effective than heretofore.

My invention is illustrated in the accompanying drawings, in whieh-Figure 1 is a side elevation of a letterpress printing machineconstructed according to my invention. Figs. la and 1b are detail sideviews. Fig. 2 is a longitudinal section of the machine. Fig. 3 is asectional elevation and Fig. 4 isa plan'of parts for throwing theimpression77 on and off. Fig. 5 is a sectional elevation and Fig. 6 is aplan of parts at the lower edge of the feed table' for presenting thelower edge of the sheet in a proper direction to be taken by thecylinder grippers. Fig. 7 is a front elevation and Fig. 8 is a sectionalelevation of parts showing the retainer, and parts for actuating thesame, for seizing the edge of the printed sheet as presented to it bythe cylinder and for delivering it to the receiving table. Fig. 8a is adetail plan view and Fig. Sl is a detail side View of parts ofthesheet-retainer. Fig. 9 is a cross section of one of the segments, itsrack, carrying rail and guide. Fig. 10 is a sectional elevation of partsfor holding up or down the lever controlling the apparatus for throwingthe impression on and off. Fig. 11 is an end elevation of the impressioncylinder with its loose toothed wheel broken away in order to show thecatch arrangement, and Fig. l2 is a longitudinal section of the same.

Fig. 13 is a longitudinal section and Fig. 14 is a cross section showingthe f parts of the end standards ot ot carry the bed of the machine,which latter consists of a rail 0.3 011 each side of the length of themachine, cross bars a4 a4, ink slab a5 and bearings a6 for the shaft ofthe large driving toothed wheel, cast together. The axis b' of theimpression cylinder b is carried at its ends in bearings c', forming theaxes of motion of segments e, the rims of which are provided with plainsurfaces c2 to run on the plain or flat portions a* of the rails a', andwith teeth e3 togear into the toothed racks a2. These segments c areconnected together firmly by a cross rail c4 under the bed of themachine, and such cross rail c4 is connected by a link CZ to acrank pine on a toothed wheel e driven by a pinionf on the driving axis f. Thenecks of the axis b of the impression cylinder b pass through thebearings orhollow axes e of the segments c, and such bearings c alsopass through bearings g attached to aframe consisting of side rails gand a cross bar g2 fixed rigidly together and carrying the inkingrollers h and stops it" for holding the cyl" inder b fast in its returntraverse over the type hed or lithographie stone, having springs t*located on the back of the side rails g, and partly recessed therein andconnected at one end to said side rails and at the other end tothe IOOstops t', fi', and such frame also carries, when used for lithographicpurposes, the damping rollers j represented at Fig. l5, in which4 casethe bed a3 d* of the machine carries a damper 7c, in contact with whichthe damping rollers j run during part of their to and fro motion. Theinking rollers, when not supported by the ink slab, run over wood railsa5* resting on the side rails a3. The side rails g of said frame runmainly clear of the side rails as of the machine bed, but the rear endsthereof rest, by the rollers g3, upon the machine side rails a3, andsuch rear ends of the side rails g are held down to the machine siderails 01.3 by the brackets or clamps g4. The impression cylinder b isheld down to the side rails as by adjustable clam ps iixed to the crossbar g2, and each consisting, according to the arrangement represented atFig. l, of a friction roller g5 carried by a bracket c/ pivoted at 9*,which bracket is adjustable in height by means of a screw Q7 passingthrough the cross barg.

In the modification shown at Figs. 13 and 14, the adjustable brackets orfram es g6 each carry three friction rollers g5, of which latter more orless may be used, and said brackets or frames, instead of being actedupon directly by the screws Q7 have springs g8 interposed between saidscrews and brackets or frames, while the latter are limited in theirupward motion by screws g fixed to said brackets and passing looselythrough holes in the cross bar g2,nuts g10 being screwed on to the lowerends of such screws. By the above arrangement the principal weight ofthe cylinder and its frame is carried by the segments c resting on theflat parts a* of the lower rails a.

The rails d are provided with flanges a7 to retain the segments c incorrect position and consequently prevent endwise motion to theimpression cylinder b and other parts moving therewith. As analternative the segments c may be provided with flanges, or the frames gmay be provided with guides working against the side rails as. By theabove described arrangement of driving mechanism a smoother and morebalanced motion is given tothe cylinder b and other parts thanheretofore.

The segments c are connected by links l to a frame fm carrying thedistributing rollers m', receiving table or board n, and arm or pin m2for releasing the sheet retainer at the required time to cause theprinted sheet to fall on to the said'table or board n.

The impression cylinder b is provided with a gripper bar b2, on one endof which is a lever b3, which is operated by a trip lever b4 at each endof the traverse of the impression cylinder b in the following manner.The frame uprights d, carrying the sheet retainer, also carry a levercam o, which, by the pressure against the lower side thereof of theirnpression cylinder bearing or other part moving with it, is caused, byits upper part, to act upon the truck b5, and thereby to give a quickmotion to the trip lever b4, which latter, by acting upon the lever b3gives apartial rotary motion to the impression cylinder grippershaftb2,andtl1ereby releases the paper on the impression cylinder b atthe precise moment when the movable jaw p* of the sheet retainer iscaused to close against the xed bar or jaw p to grip the paper. Thisclosing action of the jaw p* is eected by the top side of the truck b5coming against the under side of the lever catch p2 hereinafterdescribed.

The sheet retainer consists of the fixed bar p andthe spring gripper barp, which are carried by brackets or extensions of uprights ct of themachine frame, or such parts may be carried by brackets fixed to themachine bed side bars as; the spring gripper bar p is provided with aspring lfm* coiled around the bar, one end of the spring being fastenedto a screw on an arm pii, and at the other end to the bar p. The armpif* is located on the spring gripper bar and is fitted with a catch p2pivoted thereto, and such catch acts in connection with a fixed stop p3,so that when required the grippers p* of the spring gripper harp can beheld away from the fixed jaw or bar p of the sheet retainer and, at themoment when the paper is released from the impression cylinder, thetruck b5 of the aforesaid trip lever 54 acts upon the pivoted catch p2as above described to release it from the fixed stop p3 and therebypermit the grippers p* of the spring gripper bar p to close against thefixed jaw or carp of the sheet retainer. In the forward motion of theframe m carrying the distributing rollers m', dac., a fixed arm or pinm2 on such frame acts against one end of a lever q, the other end ofwhich acts to move the grippers p* of the spring gripper bar p away fromthe fixed bar or jaw p to release the printed sheet and at the same timeplaces the pivoted catch p2 against the stop p3 to keep the sheetretainer` open until, on the return of the impression cylinder b, it isagain released to cause the sheet retainer to grip a fresh printedsheet. The lever q works on a fixed axle g in the standard (the sameaxle carries the arm 0 for opening the grippers on the impression cylinder). The pin m2 by moving with the rollers m and receivingtable orboard n comes into contact with the lowerend of the lever q the upperend of which moves back the arm p* thereby turning the shaft p, andremoving the grippers p* from the fixed bar p to release the sheet, thelower end of the arm pik* carries the catch p? which drops against thefixed stop p3 fastened to the standard a and holds the grippers piopenuntil the next sheet is to be gripped, then by raising thc catch p2 thespring 13M* causes the grippers p* to close on the sheet.

The front of the machine has brackets r standing up therefrom, and tothese brackets the feed table s is pivoted. The lower edge of the feedtable s is a short distance away from a fixed stop or bar s', againstwhich the blank sheet of paperis fed. y The lower edge of the feed tables has a dipping motion imparted thereto by its own weight acting incombination with the following parts.

The feed table s has connected thereto an arm s2, which rest against oneend of a lever s3, whose other end rests, by a truck or roller s4,against a cam S5; thus the cam 85 causes the feed table sto be raised toits upper position when a sheet of paper is to be fed on tothe same, sothat the lower edge of the sheet, when fedon to the table, will slidedown and rest against the fixed bar or stop s; then, when it is desiredto lower the sheet to the position for it to be taken by the impressioncylinder grippers, the cam S5 allows the feed table s to dip by its ownweight. The lower edge of the feed table s has a bar s6 carried at therear ends ot' levers S7 pivoted to brackets fixed to said table and at ashort distance beyond the lower edge of the latter; this bar s is actedupon by a spring S8 to cause it to dip in relation to the lower edge ofthe feed table when required, so that fingers S9 thereon shall grip thesheet of paper on such feed table, and other lingers S10 shall cause thelower edge of the sheet to be depressed into position to be securelygripped by the impression cylindergrippers. The feed tableY s, Vinrising, brings the front end of one of the pivoted arms S7 carrying thespring finger bar s6 against a fixed stop s and thereby raises suchpivoted finger bar s6 into position to en able a fresh sheet of paper tobe fed on to the feed table s against the fixed stop s. This arrangementof parts for presenting the lower edge of the blank sheet to theimpression cylinder grippers is also applicable to other cylinderprinting machines.

A lever frametis mounted on axes t at the lower part of the front of themachine framing and acam152fixed to one arm of the lever frame z5 isacted upon by a roller 153 carried by the toothed wheel e, so as to movethe said lever frame t in one direction, the weight of the frame 15,assisted by a spring z5* acting to move it in the opposite directionuntil such frame comes to rest against a stop 156. This lever frame tcarries, as will be .hereinafter described, a finger 754, which, byacting on the under side of the plain end of the trip lever b4, releasesthe impression cylinder grippers b2 at the required time to cause themto grip the lower edge of the sheet of paper as vthe latter is presentedto the impression cylinder, and the lever frame 15 also carries, as willbe hereinafter described, a lever pusher 255, which, at the moment afterthe impression cylinder grippers ha ve seized the sheet of paper, pushesthe lever arm i2 of the stop 'and releases the impression cylinder,thereby enabling itl to rotate during its traverse motion forprinting.One of the brackets r has pivoted thereto at tf, a lever u, which, bymeans of a weighted tumbler lever u and eccentric u2, is capable ofbeing raised and lowered at its free end, thereby enabling theimpression to be thrown off or onV as may be requiredin the followingmanner. A spring catch a3 acts in one or other of the notches a4 of thelever alto 7o hold the latter in whichever position it is left by thetumbler lever u. The lever u has fixed thereto a cam a5, the frontend ofwhich is formed to act against a truck o carried by one end of a leverc, whose other end is Ypivoted at o2 on a projection from the leverframe t, and such lever o is connected by link o3 to a sliding bar o4,which carries at one end the finger# and lever pusher t5. The cam 11,5will, when in position to do so, act upon the truck o to push theslidingbar o4 in the direction shown by the arrow and, when in itsextreme position in such direction, the finger t4 and 'lever pusher t5are imposition to act respectively upon the trip lever b4 and the lever722 of the stop z", but when the lever u is lowered so that lthe cam a5is below the planeofthe truck o', such camwill miss the said truck inthe forward motion of the lever frame t, `and the spring o5 will, whenthe lever frame z5 is nearly in its most backward position, pull the bar@4in the contrary direction to that of the arrow into position for thefinger z54 and lever pusher 155 to miss the trip lever b4 and lever i2of the top i'. As the lever frame t approaches nearly to its mostbackward position, a projectionvo6 acts against the spring catch us torelease it from the teeth a4, at which time the lever a can be eitherraised or lowered as required. When the lever u is in its raisedposition, the various parts controlling the throwing off or on of theimpression, are acted upon for throwing on the impression,but whenthelever u is in its lowermost position, .the various parts above referredto are acted upon for throwing on the impression. Theleveru also, whenin its lowered position, brings aA stop 11.6 thereon into position foran arm -312 on the under side of the table s to rest against the same,by which means the dipping of said i 1o table s is prevented, therebypreventing-the delivery of a' blank sheet of paper to the impressioncylinder grippers at the time when the impression is thrown off.

The impression cylinder h has lixed on one end thereof, a toothed wheelh6, which has a few teeth cut away or absent, on one side thereof; onthe other end of the axis of said impression cylinder is mounted atoothed ,i

wheel 67, both of which wheels gear into racks a8 xed on the side barsa3, and such wheel 57 is .provided with the following arrangement ofparts for enabling it to give motion to the impression cylinderand torun free thereof at the required times. v

0n the end of the impression cylinder bis fixed a projection b8 andpivoted to the wheel 67 is an arm b9, spring bw to place itin theposition shown by Fig. ll, in which position said arm` b9. Will, by

pushing against the projection bs, give rotary motion to the impressioncylinder b, but when the impression Vcylinder has arrived at` the end ofits forward or printing motion and which is acted upon by a.

the return motion commences, the wheel c7, l

still being in gear with one of the racks a8, will revolve in thecontrary direction, but in doing so the arm b9 will recede from theprojection bs till it has completed such revolution, when the arm b9will again assume the position shown at Fig. ll in readiness to giverotary motion to the impression cylinder. If however the leveru has beenlowered to throw olf the impression, the under side of the cam 11.5will, by pressing on the truck b, disengage the arm b9 from theprojection bs in order to prevent rotary motion being given to theimpression cylinder thereby. The wheel b, on themotion of theimpressioncylinder toward the feed table s, and also when the impression is thrownoft, will, by reason of the lat portion thereof being toward the rackas, pass over such rack without gearing therewith.

'w is a brake, which may be of any suitable character, and which is usedto overcome the momentum of the impression cylinder b and therebyprevent the stop or catch b* thereon from over-running the spring stopsz' The impression cylinder b, when permitted by the removal of the stopt" from the catch or stop if, is capable of revolving and, when about tocomplete its revolution to the position shown by Figs. l and 13, thecatch or stop b* pushes down the stop 'L' until it just clears thelatter, when, by again coming into contact with the stop fi', theimpression cylinder is again locked to prevent any rotary motion thereofon its return toward the feed table.

0^ is a pusher home finger or stop, which is fixed to one of thebrackets fr or to other part of the machine frame, and which, in theevent of the impression cylinder having slightly over-run its correctposition, will, by acting against a notch 5** in, or a projection on,the impression cylinder b, insure the adjustment of the impressioncylinder to its correct position for the gripper to receive a sheet ofpaper from the feeding table s.

y is an ink duct of any ordinary character.

z is a fixed but adjustable side lay, I hangs below the feed table Vwhenthe latter is in its raised position and it is used as a guide againstwhich the paper is fed endwise so that the sheet will register.

In the modification shown at Fig. 15, which is arranged for lithographiework, the impression cylinder b and inking rollers h are similar tothose of the letter-press machine hereinbefore described, but inaddition there are damping rollers j, which travel over a damper lo andover the lithographie stone 0c to the position shown in dotted lines.The bed is also modified as shown for the increased thickness of thestone, and the ink slab a5 is proportionately extended according to therequirements; the inking rollers are of the character usually employedwith lithographie printing machines.
